Review on Multi-Purpose Plastic Razor Blade Scraper Tool - 2 Pack With 100 PCS Blades For Easy Paint And Sticker Removal, No Scratch Cleaning Of Car Windows, Glass, Wood, Floors, And More! by Robb Fillmore

I ordered this tool to use to scrape grout from a bathtub repair. it worked really well to smooth and cleanup the grout/caulking. But I also noticed when doing the job that it worked really well to clean the bathtub! The plastic razor blades seem a little smaller than standard size so this tool allows you to get around some corners, faucets, and reach small spaces. I used it a lot before having to swap sides and replace with a new blade. This set comes with plenty of blades, so it will last awhile. This will work great for bathtub soap scum, getting sticky stuff off of windows or mirrors, And cleaning the soap scum off shower doors.
